Large cold storage project for the size of the refrigeration space, the use of tons as a unit of measurement of the cooling capacity. In fact, this unscientific unit is now cubic. Let's do a simple conversion of cubic meters and tons.

   large cold storage engineering fruits and vegetables1tons5Cubic Meters, Poultry4-4.5cubic meters. After preliminary calculation, the utilization rate of small cold storage is about0.6, the utilization rate of large shelf-type cold storage is about0.4-0.5. Such1000Tons of fruit and vegetable warehouse needs5000about cubic meters of refrigerated space, such1000ton poultry meat warehouse, approx.4500cubic meters of space.

   As for the height of the large cold storage project, the large cold storage can be built in10meters or so or even higher, a more suitable height should be built13In the cold storage below the meter. Because the length of the insulation board is too long, it will increase the difficulty in the production, transportation and installation process. But my country has20The multi-meter high three-dimensional cold storage needs to be spliced together during the installation process.

   Large-scale cold storage engineering building structure type: according to the location of the cold storage, the key is long-term storage or frequent turnover and trading type cold storage? In the case of large water storage, long water storage time, sufficient land use, land cost economy, can use multi-layer civil engineering cooling

   Large cold storage project multi-layer cold storage layer with a loading and unloading platform. After entering the closed platform, it is transported to the third floor of the 2. by elevator and transported to the warehouse by forklift. In the case of short storage period and frequent daily transactions, in order to improve the efficiency of turnover distribution and rapid customs clearance, single-layer steel structure building structure and combined storage board thermal insulation structure cold storage should be adopted.

   The steel structure of large-scale cold storage engineering has the advantages of fast construction period and convenient construction. The cold storage body is rectangular and can be equipped with multi-directional loading and unloading platforms. In large cold storage, different shelf heights and types should be used according to the stored goods. The shelves of agricultural products shall be of tray type, heavy beam type and drive type. Standardized and automated pallet shelves can be built as needed.

   Example of large cold storage project refrigeration technology and project cost: new construction3000t/15000 m3Cold storage (non-controlled atmosphere storage), storage of fruits and vegetables, poultry, agricultural products and food. According to the characteristics of the goods, planning, design and construction of fruits and vegetables (0-10 ℃2) Refrigeration2000tons/11000Cubic meters, poultry meat (-18～-25 ℃）1000tons/4000cubic meters.

   Large cold storage project using single-story steel structure building, building area28m, long67mHigh cold storage8m, steel structure top height10m, the outer edge of the steel structure is lower than the top5meters, below the top5m for steel structure andEPSInsulation board enclosure structure. That is, the building structure is long.67m, warehouse width28m, unilateral platform width7m, steel structure elevation10Meters, clear height of cold storage8Meters.

   large cold storage project cold storage1876Square meters, platform67 × 7 = 402Square meters. The height is10Meters. The area of refrigerated truck and surrounding flat ground is not calculated. Only the refrigeration part is planned here.2The cost estimate of steel structure is (450-500) Yuan/m2,67 ×（28 7）=117Ten thousand yuan (including platform).

   large cold storage project cold storage costs:67 × 28 × 8 = 1.5ten thousand cubic meters,1.5Ten thousand cubic meters× 220/cubic meter=330Ten thousand yuan (including cold storage insulation, refrigeration system, pipeline electrical control, engineering cost, etc.), the Ministry of Construction is divided120Ten thousand yuan 330Ten thousand yuan. (Actual prices vary from high to low).
